I think, you have a problem ;-)

You have a data directory initialized by PostgreSQL version 7.3. Because
of this, you need a running 7.3-Server to acces to this data. But you
have installed 8.3.8.

You should now install a 7.3 - Server tu access to the data. Make a
Backup of the data-directory before!

If the 7.3 - Server is running, you can make a Backup. You should make
this Backup with the 8.3-Server (yes, you can have multiple versions
installed on the same computer and the same time)
